Hand of Fate. Part 1: On the March

I looked at this unfortunate situation. 20 nomadic centaurs. Level 21. Stats: 34, 25, 12, 17, 9, 5. And, I apologize, I dug around in the game folder. Strangely enough, I downloaded it as version 3.1 (and intentionally looked for this specific version), but in the installed version, the txt file says 3.0. It seems the problem lies in this. Can you tell me where I can download version 3.1? I already have 4 versions of Heroes 5, and it's not certain that I'll download the right one again.
